TAPPING- DEVICE FOR RECEPTACLES.

iev/aces.

Application led November 7, 1919.

To @ZZ flo/02a t may concern Be it known that l, FRANK KIRBY, a citizen of the United States of America, residing at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Tapping Devices for Receptacles, of which the following is a specification, reference being had therein to the accompanying drawings.

T his invention relates to a tapping device for receptacles, and has special reference to that type of device used for tapping barrels so that the contents of the barrel may be subjected to air pressure to cause the contents of the barrel to flow therefrom.

The object of my invention is to provide a tapping device that may be easily and quickly mounted in the usual openings in the head and side of a barrel, one part of the device being adapted to screw in the barrel head opening and another part of the device to screw into the side wall opening of the barrel, thus obviating the necessity of using two separate tapping devices.

The above and other objects are attained by a simple, durable and inexpensive mechanical construction that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein- Figure 1 is a vertical sectional view of the tapping device mounted in the head of a barrel, and

Fig. 2 is a side elevation of the device mounted in the side wall opening of a barrel.

The tapping device comprises a tapering' exteriorly screw-threaded stem 1 adapted to be screwed into the head opening 2 of a, barrel head 3, and the outer end of the stem 1 has a cylindrical head l of greater diameter than the stem 1 and provided with screw threads 5, so that it may be screwed into the opening 6 in the side wall 7 of a barrel, as shown in Fig. 2. In such position the stem 1 is completely within the barrel and the inward movement of the head 4; is limited by a peripheral ange 8 on the outer end of said head.

The outer end of the head 4L terminates in a cylindrical boss 9 and a stuiiing box 10, said stutling box having a detachable packing gland or cap 11 through which extends a discharge tube 12. This discharge tube snugly fits an opening 13 in the stuing box 10 and extends through a longitudinal bore 141 in the boss 9, the head and the stem l,

said bore being of greater diameter than the Vopening 13, so as to provide an annular passage about the tube 12 from the inner end of the stem 1 to a lateral port 15 in the boss 9.

Mounted in the lateral port 15 of the boss 9 is the inner reduced screw-threaded end of a check valve body 16 containing a conventional form of spring pressed inwardlyl opening check valve 17 which permits of air being forced into the port 15 and the bore 14e and prevents the escape of air or liquid through said valve body.

Mounted on the outer end of the valve body 16 is a coupling member 18 to which is suitably connected a hose or conduit 19 adapted to conduct air or other fiuid, under pressure, to the tapping device. Vhen air is forced through the tapping device onto the surface of the liquid within the barrel the liquid is forced through the discharge tube 12 which may extend in proximity to the bottom or side wall of the barrel opposite the tapping device.

attach considerable importance to the fact that the body of the tapping device is constructed so that its stem 1 may be mounted in small holes of various diameters and its head 5 mounted in a bung or other large opening of a barrel, thus permitting of a single device being used where heretofore tapping devices of different sizes were required.

For instance, steel barrels used for shipping gasolene and combustible liquid generally have interiorly screwthreaded bung openings and at present the diameter of the bung openings varies in the different makes of barrels on the market, so it is necessary to have different sizes of tapping devices. Now, with my device it is possible to tap different makes of barrels.

@ne embodiment of my invention has been illustrated, but it is to be understood that the structural elements are susceptible to such changes as fall within the scope of the appended claims.

lhat 1 claim is:

1. A tapping device comprising an exteriorly screw-threaded tapering stem adapted to enter a small hole, an exteriorly screwthreaded head carried by the outer end of said stem and adapted to enter a hole comparatively larger than the hole for said stem, said head and stem having a bore therein `through which is adapted to extend a tube of less diameter than the bore, and a check vulve body Communicating With the outei1 end 01"' the bore and adapted to admit a` `fluid under pressure to said bore.

2. A tapping device Comprising an exteriorly screw-tlnead-ed tapering stem, an eX- terioi'ly screw-threaded head carried by the outer end Vof said stem and provided with L peripheral flange adapted to limit the inward movement oi" the head when mounted in an opening, a boss carried by said head and having an opening formed therein communieating with the longitudinal bore in said stem of greater diameter than said boss opening, a tube extending through the boss opening and the stem bore, :L cheek valve body communicatingwith the stem bore and supported by said boss, and a conduit conneoted to said cheek valve body and adapted to conduct air under pressure to the stem bore.

In testimony whereof I affix my signature in the presence of two Witnesses;

FRANK KIRBY.
